Lego Green Lantern Power Battery

As a fan of Geoff Johns’ Green Lantern, when I was seeking ideas of things to build, it was only natural to build the Green Lantern power battery that Hal Jordan uses to power the ring with which he battles evil and foes such as the Sinestro Corp.  Of course, it wouldn’t be worth building if I couldn’t power the ring like Hal, so the inspiration was born.

The first stage of this project was to prepare the electronics. The obvious choice was to use an Arduino with an RFID reader in the front of the lantern.  With a considerable amount of strife, and a ruined RFID reader, I was able to read an RFID chip with the hardware. The chip was implanted within a Green Lantern ring that had been given away by comic book stores earlier this year.

The Lego Sphere

Once the Arduino was ready, it was time to start building the Lantern itself.  The first stage was to build the Lego sphere that made up the main body of the power battery, leaving holes on the sides for the lantern extrusions.  A hole was also left in the top to allow the top part of the lantern to open to access the electronics.  The arduino was placed in the body, and the RFID read and LED lights were added as the front of the lantern was built out.  The power cable was run through the back and the rear was built out with a hole left for the cable.

When building the power battery, I veered from the actual design in two places. The first is the handle. Hal Jordan lifts the lantern with a handle that runs off its sides, but the weight of Lego and the lack of strength of the handle seemed like a poor idea in case someone got the idea lift it by the handle. The second design change was to add a Green Lantern symbol in the front of the Lantern so it would glow when the lights fade in and out.

By combining plastic bricks and technology, it becomes possible to create an interactive experience that would not be possible to bring fictional items like the Green Lantern power battery or the TARDIS to life.  Upon completion of the Green Lantern, friends were impressed and asked if they would one day see the rest of the Lantern Corps colors, and my only answer was only time will tell.
